    Photo Number 54 - The basics
    are in place.
    Take note that the float insides
    are coated with Green
    Cuperenol preservative. Why?
    Well, during rainy weather with
    an old canvas tarp covering
    everything, it leaked. Water filled
    inside the floats.

    Solution.....Frank Sasine said to
    drill a 1/2" hole in the bottom of
    each float. It didn't seem right at
    that time, but the float frames
    had leach holes at the bottom of
    each frame and any water would
    flow to the keels lowest point.
    That is where the small hole was
    placed, and guess what? It
    worked. After the construction
    was continued, a plug was
    bonded through the keel in the
    holes and later glassed over
    from the outside.
